Hello,
I have a problem with multiple USB2 devices. After purchasing a new
motherboard,
some USB2 devices (specifically audio devices and bluetooth dongles) do
no longer
work when connected to a hub, even if they are the only device on the
hub. They do
work when they are directly connected to an USB (2.0 or 3.0) port of the
machine.
The error I am getting with the hub in between is "Not enough bandwidth
for new
device state". Here are example kernel messages for a bluetooth dongle:
Mar 14 08:12:33 mini kernel: usb 1-4.1: new full-speed USB device number
15 using xhci_hcd
Mar 14 08:12:33 mini kernel: usb 1-4.1: New USB device found,
idVendor=0a12, idProduct=0001, bcdDevice=31.64
Mar 14 08:12:33 mini kernel: usb 1-4.1: New USB device strings: Mfr=0,
Product=0, SerialNumber=0
Mar 14 08:12:33 mini kernel: usb 1-4.1: Not enough bandwidth for new
device state.
I have only one single USB controller:
00:15.0 USB controller: Intel Corporation Atom Processor C3000 Series
USB 3.0 xHCI Controller (rev 11)
I am using kernel 5.0.

The C-Media sound device is directly connected to the machine and is
working.
The BT dongle is on a hub and does not work. If I connect the C-Media device
to a hub, it will also produce the "not enough bandwidth" error. Can
anybody help
me to debug this problem further?

Georg
